Tires? (Only if they are the same size....)
///M3's come with 17x8 with a 5x120mm bolt pattern, don't even think the tires would be swapable.
But yeah I am with him the only things that are swappable would be non-engine things like seats, shift knob, the only "engine" thing I could see would be .... possibly the alternator if you made a custom bracket or somthing.
